CONSTITUTION:A bottom surface part 28a of a container is provided with an agitating vane 30 for kneading raw material and a fixing table 31 for a container 28 is formed into a cup shape having a down-ward directed opening. As a composing material for the container 28 and the fixing table 31, a vibration-proof material is used so as to reduce a shocking vibration occurred during the agitating operation. The vibration-proof is constructed such that a resin film 37 having a relative high thermal-proof characteristic is sandwiched between the two aluminum alloy thin plates 35 and 36. In addition, one resilient packing 38 made of heat-resistant silicone rubber or the like this held between the bottom part 28a of the container and a ceiling part 31a of the fixing table. A similar packing 39 is also installed at an abutting part between the fixing table 31 and the bottom surface 18 of the heating chamber. Use of the vibration-proof metallic plate causes a vibration shock to be hardly transmitted and also a resonation is restricted, so that a transmittance of the vibration is also reduced by a packing from the heating chamber to the main body.

IPC: G01N21/892
Filed: 1999-06-25
Abstract: PROBLEM TO BE SOLVED: To obtain a print image with high quality by a 2nd visual range optical sensor reading a visual area light different from a read wavelength band of a 1st visual area optical sensor so as to sense dust or a flaw of a film. SOLUTION: A scanner 11 applies primary reading (preliminary scanning) to a film by using RGB and 'GR' lights. A histogram of obtained preliminary scanning image data RGB and 'GR' is calculated and a threshold value for dust/flaw discrimination is calculated. After the preliminary scanning, two thresholds Dth1, Dth2 are calculated for the discrimination, the scanner 11 conducts the fine scanning by using the RGB and 'GR' light. A new threshold Dth3=f(DR.DG) is generated for each pixel by using a value like a function approximation for a density (DR) of a R and a density (DG) of G for polynomial approximation, and in the case that the fine scanning DRG (density of GR) is higher than the Dth3, presence of dust/flaw can be discriminated.

Title: Antivibration floor
Inventor: OKUZAWA MASAYUKI
IPC: F16F15/04
Filed: 1987-07-17
Abstract: PURPOSE:To reduce the low frequency vibration in particular by placing a membrane at the surrounding inside between the lower side of a surface material and the upper side of a lower material, and furnishing an enclosed air layer surrounded by the surface material, the membrane, and the lower material, in an antivibration floor to reduce the floor shock sound. CONSTITUTION:Between the surrounding insides 1b and 2b at the lower side 1a of a surface material 1 and at the upper side 2a of a lower material 2, both of which consist of a material of a wooden high polymer or the like, of several to ten-odd mm thick consisting of rubber, sponge, or the like, is placed, and an enclosed air layer 4 is formed therein. As a result, when a heavy good such as a piano is loaded on a body 5 through this antivibration floor, the shock inflicted to the surface material 1 is vibration-insulated by the air layer 4, being held by the membrane 3 and the air layer 4, and the vibration is hardly delivered to the lower material 2. And at the same time, the vibration can be absorbed resonantly. In such a way, the floor shock sound can be reduced, and especially, the low frequency vibration which determines the sound shielding level can be decreased.

Abstract: PROBLEM TO BE SOLVED: To allow a battery pack, for use as a backup power supply using a number of batteries during power outages, to stably maintain its performance over a long period even in a severe service environment by covering the outer periphery of each battery with an insulator made of an elastic material excellent in heat resistance. SOLUTION: In a battery pack, in which cylindrical batteries 1 are arranged in a plurality of straight lines and the batteries electrically connected in series with one another by connecting plates are enclosed in a container 4, a cylindrical sheet of insulator 5 made from a polyethylene 0.2mm thick is used to cover the peripheral surface of each battery except portions around the connecting plates 3.  Thus even if the battery pack is used as a backup during the power failure of a train, the impact of collision that may occur between the batteries as the result of vibration during running of the train is eased by the elasticity of the insulator 5, and since the heat softening point of the insulator is as high as about 125 deg.C, thermal degradation can be inhibited, so that the performance of the battery pack can be maintained stably over a long period even in a severe service environment such as a train.
